' IHVIPZRO'VEI) GRAIN-FAN.-

The Schedule referred to inthese Letters Patent and part of theieame Toan whom may concern:

Be it known that I, JAMES MoPrrAIn, of Charles 1 Gity,in the county ofFloyd, and in the State of Iowa, have invented certainnew and usefulImprovements in Grain-Fan; and do hereby declare that the following is afull, clear, andexac't description thereof, reff erenc'e being had tothe accompanying drawings and part of this specification. I V

The nature of my invention consists in the arrange naent andconstruction of a grain-fan, in providing the any desired angle, as willFigure 1 is a perspective of my invention.

Figure 2 is a similar view of the bag-holder detached from the frame. 14

- Figure 3 is a section view of my grain-fan.

Letter A represents the frame,whioh is constructed of any desired shapeor size, and which has the fan B placed in its front end. a

Extending upward from each side of the frame is a standard, 0, whichsupports the revolving buckets D immediately above the hopper, so thatas the grain falls from the spout it fills the buckets, andthns causesthem to revolve, thereby generating the power which is to revolve thefan.

4 Attached toone end of'the'shaft E which passes throughtheovershot-wheel D, and which has its hearings upon the standard 0, is'apulley, F, around which passes the belt G, and thus communiL-atestheSecured to the shoe H there are two screens,,one-

ofwhich is stationary, while the second one is loose, and can beadjusted at pleasure. l

The stationary screen llis smaller than the adj ustable one K, which ispivoted to the shoe by a'pivot, L, ateach corner, so that it can belowered or raised in such a manner as to decrease the number of'screens"usually required ingradingthe grain.

When the screen K is; lowered, so as tohe'on a" level with the smallerone, the whole quantity of grain will flow out at the front end underthe fan.

' When raised only partly, then but a portion flows to the front, whilethat on the stationary screen flows into the 'trough'M, placed justundcrits lower end,

"and passes out the side, and when raised to its full height, the largerportion flows to the front, and only a small portioninto the trough.

In one or each side'of the shoe their 'is a'circular slot, a,cut-,through which a small screw-rod, 1), projects from the side of thesoreen'-K,'and is provided with a nut-,'c, so that the screen=canbeadjusted and held at any desired point.

to the lettersof reference marked thereon making a' i Q pared for. it..screens with pivots .so that they may. be adjusted at hereafter be morefully set I sift the grain.

v the wings at any desired point-1- Securd to the rear end of the shoeis a trough,'1 l,

which is intended to catch all the grain which may be driven over theend of the screen.

\ The'r'nouth. of this trough is lower than the opposite end, and has. anumber, of perforations made through it, and is provided on its underside with a movable slide, d, so that the openings may be partly orentirely closed.

All the larger and coarser dirt, together with the, straw, will flowover pastthese openings, whilethe grainwill drop through them into areceptacle prevIf desired, there may be .one or more' additional spoutsplaced under the one N, so as to still farther Hinged to the top of thetrough there is an, adjustable cover, 0, which may be secured at anydesired point by means of the rod i, so as to prevent the chaff frombeing driven into the trough, thus making the grain fstill easierto-clean;

1 Passing through a loop, 0, attached to the side of the frame, atthefront end, and througha hole in the post I, is a wooden bar or .rod, P,to which thebagholder is attached.

In the rearside of the bar there is a dovetail groove out, so thatth'eupright standard R, to which the two wi'ngsof the bag-holder arefastened, can be raised or lowered-to any desired-height, or canbeentirelyremoved.

To the top of the standard B there are secured two wings, S', whi'chform the holder, one of them being stationary,'while the other isloosely pivoted, and has a lever, '1, attached to it, so thatit'canbemoved' back and forthvin order to bring the ends of the wings 1nearer orfarther apart, so 'as to accommodate the mouthsofdifferent-sized bags. These wings may be oonstructedof sheet-iron, andhave metal braces passed aroundtheir sides, so as to strengthen them,upon which sharp points are formed, so that the bags can be moresecurely held.

Upon the top ofthe standard R there is placed the serrated plate V,which catches the lever, and holds If it is. desired, the whole bottomof regular sieve. 3 V

Having-thus described my invention,- What 1 claim, and desire to secureby Letters Patent, is'- 1.;The perforated trough N, attached-to the rearend of the shoe, and provided with the slide 11, substantially'in themanner and for vthe purpose set forth.

' 2 The adjustable cover 0, provided. with the rod i, for securing ,itat any desired point, in combination with the trough N, substantially asspecified.

" 3.;lhe adjustable screen K, provided with the-pivthe trough N may beperforated from end to end, so as to form a ots L, so that the flow ofthe grain may be changed l 6. The standards 0, shaft E, revolvingbuckets D, from the front end to the side, substantially as specil andpulley F, when arranged to operate substantially in the manner and forthe purpose specified.

In testimony that I claim the foregoing, I have here- 4. In combinationwith the screen K, provided with pivots L, the screen I and trough M,substantially as unto set my hand this 8th day oiNovemher, 1869, setforth. J AMES MOPHAIL.

5. In combination with the screen K and pivots L, the circular slot a,screw-rod I), and nut or thumb- Witnesses: screw 0, when so arranged asto support the screen at GEO. F. BoULToN any desired point,substantially as described. A. H. MCKALLOR,
